To all whom t may concern Be it known that l, JAMES A. LANSING, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Ranges; and I do hereby declare the following to be a full, clear, and exact description of the'same, reference being had to the accompanyingA drawings, formingpart of this specification, and to the figures and letters of reference marked thereon.

This invention relates to improvements 1n domestic ranges, particularly of the type dis closed in my prior Patent No. 1,021,640, granted December 22, 1914.

In ranges of the type therein disclosed, the ordinary open gaseous fuel burners and oven are supplemented by a firebox adapted for the consumption of any variety of solid fuel. Exposed to the combustion chamber ou one side is a Water back, a second combustion chamber in which gaseous fuel burners are arranged being provided on the other side of the Water back, so that Water in a single reservoir'can be heated by either gaseous or solid fuel.

The object of the present improvement is to provide a construction permitting the utilization of coils in which the Water can be heated by the consumption of either solid or gaseous fuel, or both.

ln practice it has been found that coils are very much more satisfactory for/ heating Water than the ordinary Water back, because a much larger area of water is brought under the influence of the heat, and the opportun nity offered for circulation of the Water through the coils permits a very rapid absorption of heat, bringing the Water in the boiler to the required temperature with greater rapidity than can be obtained by the use of the ordinary Water back. ln my improved construction the coils are so arranged Within the stove that they may very readily be removed bodily from the stove by simply removing one of the outside panels.

A full understanding of the nature and objects of the invention will be attained from the following detail description taken in connection with the accompanying drawings, illustrating a construction embodying the invention in a preferred form and the novel features thereof pointed out in the appended claims.

ln the drawings, Figure l is a longitudinal section of a range made in accordance with the present invention; Fig. 2 is a top plan view of the combustion chambers with certain of the parts shown in section; Fig. 3 is a transverse section onY the line 3&3 of

Fig. i; Fig. 4 is a fragmentary section on' the line of Fig. 3; and Fig. 5 is a fragmentary longitudinal section of a range having a modified form of construction.

Referring more particularly to' the drawings, in which similar characters of refer.-

construction.

The products of combustion from the oven burner A into a liue bor; lli, through an opening D at the back of the range. The draft may be controlled by a suitable plate damper D2 mounted on an' operating rod D3 which extends transversely across the range and through the front panel to permit it to be grasped by the hand. To insure a slight draft, even when closed, the damper plate D2 is preferably perforated. Such a construction is particularly desirable in gas ranges, since it insures the passing off of poisonous gases under all conditions. The flue box is located at the back of the range directly beneath a flue E through which the products of combustion pass into the atmosphere.

i'ciqcated at one side of the oven is a fire :box li adapted for lthe consumption of solid fuel. This lire boX embodies the usual coinbustion chamber and has three of its sides lined with fire bricks F. The fuel is sup ported by grate bars F2 located in the lower `portion of the fire box. In the form of the invention shown in Figs. 1 to i, inclusive, the fire box F is separated from the oven A and open burners B by a vertical partition G, this partition being provided with a de fleeting plate G located on the side of the fire box and extending beneath the grate `bars lf2 for directing the ashes and clinlrers into an ashpit H beneath the fire box. @n the opposite side ofthe lire bei; from the oven A, is a combustion chamber K for the burning of gaseous fuel. This chamber is separated entirely from the fire box by a partition I to prevent dust and clinkers from nding their way into the same. On its outer side the combustion chamber is closed by the outer wall of the ran 'e which is conveniently a hollow door I having slide control dampers, preferably upper and lower dampers K2 K3, which provide a means for controlling the supply of air admitted to the chamber K through the inner door opening K4. A series of openings K5 in the wall K6 permits air to flow into the combustion chamber at all times.

Within the combustion chamber K, is a series of gaseous fuel burners L. These burners are preferably made long enough to extend transversely across the range through the chamber K, and are arranged in spaced superposed relation. The burners may be conveniently supported at their outer ends in a removable front plate or door K7, and at their inner ends upon spaced brackets K8 secured to the back wall of the combustion chamber K. Gaseous fuel is supplied to all the burners by a manifold L and the amountI of heat within the combustion chamber can be conveniently regulated by providing each burner with a suitable cut olf valve L2. The manifold L is. provided with a coupling L3 connecting it to the main pipe line. This arrangement of the burners enables them to be removed bodily from the combustion chamber by simply unscrewing the` coupling member L3 and removing the front plate K". The invention provides means for heating water either by the burners L or the combustion ofsolid fuel in the fire box F. In the present improvements this is attained by the use of a heating coil extending into both the gas burner chamber and the hre bo'x. The pipe M leading from a suitable domestic boiler, not-shown, enters the chamber K preferably from the rear and extends directly above the lowermost burner L throughout practically its entire extent to the front of the chamber K, whence it passes through a slot I in the partition I into the firebox. In the fire box the pipe M extends transversely of the stove to the rear and back again forming a coil M2, which again passes into the combustion chamber K through the second slot I2, the continuation M3 of the coil extending di` .rectly above the second burner L and coiling back over and throughout the extent of the --third burner L, whence it again passes through the slot I3 into the fire box, forming therein a second coil M4 arranged above, the coilI M2. The coil M4 passes through the v partition I hack irto the combustion chamber K through which it extends, and passes out of the chamber at the rear and back t' the boiler. Suitable pipe couplings Ms M heating of the water may be obtained either v bythe consumption of gaseous fuel in the combustion chamber K or the burning of solid fuel in the fire box F. The above arrangement will be found very useful in heating water when ther'e is no fire in the lire box, since by lighting the burners L the water circulating through the coils can be very quickly heated. Under ordinary conditions, when there is a iire in the lire box F, it will not be found necessary to employ the gas burner L for heating the water, thc coils within the irebox being sulicient for this purpose. 'They will be found very useful, however, in quickly heating the water just after a fire has been lighted in the iire box@ the combined heat of the two combustion chambers being great enough to heat all the water in the boiler in a comparatively short space of time. When the water in the boiler is brought to a sufiiciently high temperature, the''gas burners may be extinguished and the heat in the fire box will be found quite sufficient to keep the water hot.

The present arrangement will be found to be of great value in domestic ranges, especially in modern kitchens, where there is ordinarily not very much space, since it combines in, a single unitary construction all the advantages of a coal range and agas water heater.

In the exceedingly small kitchens of today the improved range will be found very valuable since it does not take up any more space than a range of ordinary construction. At times, it will be found desirable to direct the heat and products of combustion from the chamber K into the fire box F, for instance, when incinerating garbage, or at other times, when a large quantity of heat is desired. For this purpose, the partition I is provided with a plate damper N located near the top and controlled by a damper rod N. When the damper N is open, the heat from the chamber K passes directly into the upper portion of the lire box F. Under normal conditions, the products of combustion from the chamber K pass through an opening O located at the rear, into the flue box D. The draft may be controlled by a plate damper O, operated by a rod O2.

In Fig. 5 I lhave shown a modification.

The gas burner chamber K is located between the oven A and the fire-box F; the

pipe M enters thel chamber from the rear and passes in like .manner back and forth between the chamber and fire box forming similar heating pipes M above the gas burner L and vertical coils M2 along the partition P. The flow of the products of combustion is similarly controlled by dampers N and O. To support combustion within the chamber K air is admitted through air openings R.

While I lhave shown and described a certain specific embodiment of my invention, it will be understood that the same is not to be limited to the details of construction, but on the contrary is capable of 4modification and variation within the scope of the claims.

That is claimed is:

1. In a range, the combination of a fire box for the consumption of solid fuel, a gaseous fuel chamber with gaseous fuel burners in said chamber, a partition separating the re box from the gaseous fuel cham1 ber, and a continuous water circulating medium having coils extending directly over the burners in the gaseous fuel chamber and coils in the fire box lying against the separating partition whereby water may be heated by the combustion of fuel in both the fire box and the gaseous fuel chamber.

2. In a range, the combination of a lire box for the consumption of solid fuel, a gaseous fuel chamber with gaseous fuel burners in said chamber, a partition separating the fire box from the gaseous fuel chamber, and a continuous water circulating coil extending alternately back and forth from the gaseous fuel chamber into the fire box, the coils in the gaseous fuel chamber lying directly above the burners, and the coils in the lire box lying against theV separating partition, whereby water may be heated by the combustion of fuel in both the re box and the gaseous fuel chamber.
